Hello

I'm trying to render in 3D what I usually plot by image(), or image.plot()
from the library fields, followed by a map("world",add=TRUE) type of
command. More concretely, I have a field of temperature values, for a given
geographic area, and I would like to plot a 3D surface whose x and y axes
consist of longitude and latitude values and whose height and color-coding
correspond to the temperature values but also -- and here is the problem --
superimpose a map of the region.
persp() can easily do the color-coded surface but I cannot figure out how
(if at all possible) to overlay geographic boundaries, in this specific case
a simple map of the land area outlines.

Thank you in advance for any help

Claudia
